Back in the long-ago days of 2019, the Alabama Shakes leader Brittany Howard released her first-ever solo album Jaime. The record was bracing and personal and soulful, and it’s had a long tail. Since she released it, Howard has performed in all sorts of prominent spots, including the last two Grammy Awards ceremonies. Today, she’s announced an all-star remix album, which will feature reworked tracks from Jaime and which will be out next month.
